AF patients on NOACs have higher stroke rate, study finds

Phasing out warfarin use among patients with arrhythmia may be contraindicated

Patients with atrial fibrillation (AF) taking non-vitamin K antagonist oral anticoagulants (NOACs) may be at a higher risk of ischaemic stroke than those on warfarin, a large study suggests.

Although at odds with previous research, the results suggest a need for more intensive monitoring of levels of anticoagulation among patients taking NOACS, the authors said.
